Autoclave Dental

we're using the autoclave in dental office
i wanted to adjust the temprature, pressure and time
i rea that the time should be 15 min.
the Q is :
is that 15 min for the whole procedure??
or it's only for sterlizating phase, excluding the heat-up n cooling down phase ??
or only the sterlizing phase ?
plz answer , it's important
even if u know some sites that helps

thanks

15 minutes should be the actual sterilizing time for instruments, after the pressure has built. It doesn't count the time that the pressure is building up or the cool down phase. So it may take 1/2 hour or so to run a load.
